CHARRlNG-TOOL FOR ORNAMENTING WOOD.

SPECIFICATION forming part of Letters Patent N 0. 658,591, datedSeptember 25, 1900.

Application filed November 13,1899. Serial No. 736,784. (No model.)

To all whom it may concern.

Be it known that 1, JOHN SCHLEGEL, a citizen of the United States,residing at New York, borough of Manhattan, State of New York, haveinvented certain new and useful Improvements in Oharring-Tools for Ornamenting Wood, of which the following is a specification. J

This invention relates to that class of tools which are used forbranding purposes and by which a design may be burned in wood, leather,&c., as in pyrography, so that the charred delineations in the wood,patterned after some suitable design, produces what is known as apyrogravure.

The object of the invention is to simplify devices of the describedclass and to provide a tool which is both durable and economical andwhich is specially designed for the use of amateurs.

My invention consists of certain features of'construction to behereinafter described and then claimed.

In the accompanying drawings, Figure 1 is a side elevation of thecharring-tool. Fig. 2 is a plan of the same. Fig. 3 is an enlargedlongitudinal section of the front portion of the same; and Fig. 4 is asection on line 44;, Fig. 1.

Similar letters of reference indicate corresponding parts.

Referringto the drawings,A indicates a Bunsen burner provided with agas-supply tube or tubular extension A, in the plugged end aof whichturns a regulating-valve B, having a minute transverse opening I), whichis adapted to register with the minute gas passage or orifice I) throughthe plug a. The regulating-valve B is provided with a head or button B,preferably of non-conducting material, such as vulcanized fiber, andwhereby the Valve may be turned, so as to regulate the size of theflame. The tubular extension A of the Bunsen burner is in line with themixing-tube and is of such length as that a sleeve 0, of cork or othersuitable material, may be placed thereover to form a handle or grip. Bymaking the sleeve 0 of non-conducting material the hand is preventedfrom being burned. The outer end of the plug dis screwthreaded, so as toreceive a female thread on the mixing-tube D, provided adjacent to theorifice h with air-inlet openings d and at its outer end with ajet-orifice d, so that said mixing-tube will form an alined continuationof the elongated tubular portion A of the Bunsen burner.

A post or socket-piece E projects from one side of the forward end ofthe mixing-tube D and receives the tail end e of a charringstylus E, aset-screwf being screwed into the socket, so as to bear against the tailend 6, and thereby hold the stylus in position. As clearly shown in Fig.3, the stylus is bumped up at e, and its working end is formed with alaterally and outwardly projecting toe 6 The directly-heated portion ofthe stylus between the hump e and the toe e is slightly inclinedrelativelyto a line perpendicular to the axis of the Bunsen burner andis located in line with said axis; but the working toe e is at one sideof the jet-orifice d of the burner and does not receive the direct flamefor evident reasons. The V-shaped middle portion of the stylusthat is,its humped portionis for the pu rpose of bringing the portion to beheated in line with the Bunsen burner, so that the flame strikes saidportion above the toe e Said humped or V-shaped portion has its branchbetween the approximately straight tail end 6 and its apex of lesslength than the other branch,while the parts of the stylus all lie insubstantiallyone plane, at nearly right angles, so that the flame is notdeflected toward the toe, but envelops the stylus at the point ofcontact.

By means of the set-screwfthe stylus E maybe readily adjusted toward oraway from the jet-orifice of the burner, so that the same may be heatedup to a greater or less degree, according to requirements. When thestylus is hottest, the shades may be put in, as the wood will beconsiderably charred and blackened, while the lights may be put in whenthe stylus is farthest from the jet-orifice, as it will simply scorch ordiscolor the wood. The point of the stylus may also be heated to agreater extent than if its tail end e were straight, owing to the factthat the same is slightly curved or inclined, so that the farther thestylus is moved in the nearer will the toe e be moved toward the axis ofthe burner.

Projecting laterally from the side of the Bunsen burner adjacent to itsvalvethat is to say, at the forward end of the tubular ex tension Ais arest-piece F, which is broad at the base, so as to hold the tool steadywhen rested upon a table or Work-bench.

When the tool is to be used, it is attached to ordinary gas-tubing G, ofcourse leading from a suitable gas-supply, and the valve opened, so thata suitable quantity of gas and air will, as usually in Bunsen burners,be mixed within the mixing-tube D. The mixed air and gas is now lightedand the stylus heat-ed, the flame being regulated by the valve.

The rest-piece F has the advantages that the tool can be rested on asupporting-surface without injury thereto, that the flame does not haveto be extinguished each time the tool is laid down, and that the stylusmay be always kept heated for use, no matter what interruption in thework may require the laying down of the tool.

The parts of the tool are few, and consequently the tool is simple andcan be readily directed, so that the burning of the design or device inthe Wood can be accomplished with facility and a superior pyrogravureproduced.

Having thus described myinvention,what I claim as new, and desire tosecure by Letters Patent, is-

The herein-described charringstylus, consist-ingoi'anapproximately-straight tail end,
